Vaccination is the best protection against chickenpox and its complications. Chickenpox, also known as varicella, is a highly contagious disease caused by a virus. This virus remains in the organism and can be reactivated years later, causing shingles.
This vaccine is recommended for everyone aged 1 year or older who has not been vaccinated or who has not had chickenpox.
For people aged 50 and older, the shingles vaccine (Shingrix) is recommended instead of the chickenpox vaccine. In addition, women who are given the chickenpox vaccine must avoid becoming pregnant in the month after vaccination.
People who are vaccinated against chickenpox probably have a lower risk of getting shingles.
